Thank you Joseph!  This really helps.  I have seen parts of this when I tried making one of my machines a dhcp server, but I could not succeed :(, I had port forwarding enabled and saved the iptables, but something else was screwing up.  

When we start we see if iptables service succeeded or not.  How about the other part:

ip_tables: (C) 2000-2006 Netfilter Core Team
nf_conntrack version 0.5.0 (16384 buckets, 65536 max)
CONFIG_NF_CT_ACCT is deprecated and will be removed soon. Please use
nf_conntrack.acct=1 kernel parameter, acct=1 nf_conntrack module option or
sysctl net.netfilter.nf_conntrack_acct=1 to enable it.

What is CONFIG_NF_CT_ACCT and why is it being depracated?

Thanks for your response.  IT is what I was looking for.

Regards,

Antonio
